"My blood sugar levels rise higher than usual when I eat, could it be because of my Covid vaccine (Astra Zeneca) that I received on Sunday, April 18th?"

It is not a known side effect of the Astra Zeneca Covid-19 vaccine for your blood sugar levels to rise. However, receiving a vaccine can trigger an immune response in your body, which may temporarily increase your blood sugar levels, similar to when you are sick or have an infection. If you are diabetic, it is important to monitor your blood sugar levels closely during this time. If you have further questions, feel free to reach out for more information.
